I am having a small wedding party, a Matron of Honor and Best Man, but I want to play Marry Me by Train for the processional so I was wondering if I could send some of the family members down while it was playing. I was thinking, FI parents, my Grandma (Dad's mom) my Aunt who will represent my Mom and then my Step Mom, then finally my MOH. Or should I just start the song playing early and then send MOH down halfway through and just let the song play until it is over?
